...and if Earth Day became a religious holiday (which I doubt), what would be the harm in it? According the the Judeo-Christian story, humankind was given dominion over the earth. That doesn't mean we have dominion so we can do what we like to the earth and it's inhabitants; it means we are give the CARE of the earth, to protect and love. If that's not religion, I don't know what is.
